## How to encrypt text using Xor

This is not meant to offer protection, but if you want to say hide text by disguising it, then using Xor for reversible encryption will do the trick. It relies on the principle that if you Xor A and B to get C then you can Xor C and A to get B or Xor C and B to get A.

I wrote a short program and tutorials to demonstrate taking a single bit of text then disguising it. To make it more challenging, I only used Xor values from the range 0-255 that had four or more bits with 1 in it, for example 15 which is 00001111 in binary.

You can find the tutorial How to do Xor encryption in C. Please note this is only a very light weight encryption method so don’t use it for anything too important!
